physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day to optimize growth. 13 C values suggesting that the depth-cycled kelp were not nitrogen-deficient and assimilated nutrients from deep water. The researchers used a depth-cycling approach—i.e.,

ARPA-E awards $2.1M to Marine BioEnergy for open ocean farming of kelp for hydrocarbon biofuels

Green Car Congress

Marine BioEnergy, Inc. Part of the gas can also be used to produce the hydrogen (by steam reforming and water-gas shift) needed to upgrade the biocrude via hydrotreating. Oil tankers can be filled with high-value biocrude at the harvesting sites in the open ocean, making the whole process carbon-neutral in the global environment.

KAUST team devises electrically-driven membrane process for seawater lithium mining

Green Car Congress

As lithium possesses one of the smallest ionic sizes, we considered that it could be technically feasible to use a molecular sieving membrane to enrich lithium and to remove multivalent ions at an affordable energy cost. After enrichment, the lithium can be readily extracted using the conventional precipitation method. —Li et al.

Forecasting the Ice Loss of Greenland’s Glaciers With Viscoelastic Modeling

Cars That Think

As the leader of the Modeling Group in the Section of Glaciology at the Alfred Wegener Institute (AWI) Helmholtz Centre for Polar and Marine Research in Bremerhaven, Germany, Humbert works to extract broader lessons from Nioghalvfjerdsbræ’s ongoing decline. This basal water system is poorly known, though we can see evidence of its effects.”
